I have been commissioned to build a headboard. It is being constructed

Cherry. The basic design will be Federal.

The main panel between the posts has to be wider than any of my clamps
capicity. I could have screwed some of my old pipe clamps together but
I still did not have enough. I needed to clamp in 4 locations a
distance almost 74", so not even my 6' clamps would work.

Any way I made my 40"+ clamps work.

Then center piece on top was simply resting on top only being held in
place by the opposing forces of the clamps.

Bessey makes a widget that splices two parallel clamps end-to-end. It
might work for yours, if they don't have a similar widget.
